For the purpose of tracking orders, we need to add options to the order processing. Whenever we ship the order, we need to have a way of marking each separate item in the order as shipped. We also need an option to marking the whole order as shipped, however that option should be unavailable before each item in the order is marked as shipped. Once the whole order is marked as shipped, the email should go to the customer with the tracking number and the text we provide.
Please be advised, that you will have to work offline. I.e. we will email you all the files you need to complete it, but we will upload the actual result to the site ourselves.
